Description

Technical Field

[0001] This utility model relates to the field of fireworks display technology, and in particular to a fixing structure for fireworks display shells. Background Technology

[0002] The fireworks cannon tube is an important component of fireworks displays. It is a device specifically designed to load and launch fireworks shells. It is usually made of high-strength materials to ensure that it can withstand the enormous pressure and high temperature during launch. The design of the tube allows the fireworks shells to explode at specific times and heights, creating beautiful patterns and colors. The fireworks cannon tube typically includes a tube body, a launch port, and a bottom cover. The tube body is the main part of the tube and is usually made of seamless steel pipe or high-strength alloy. The launch port is used to load and launch fireworks shells, and its design should ensure that the fireworks shells can smoothly enter the tube and be launched stably. The bottom cover is used to seal the bottom of the tube to prevent gas leakage and ensure safety during launch.

[0003] The existing fixing structures used for fireworks shell tubes have the following drawbacks: First, the current fixing structure design is often cumbersome, requiring professional personnel to perform lengthy and meticulous operations to complete the installation or disassembly. This not only increases the difficulty of operation but may also lead to an inability to respond quickly and effectively in emergency situations. Second, when multiple fireworks shell tubes need to be installed, each tube needs to be fixed individually. This not only increases the complexity and workload of installation but also reduces the efficiency and accuracy of installation. In addition, due to the lack of connection and coordination between the fixing structures, it is difficult to ensure that all tubes can maintain a consistent level and angle after installation, thus affecting the launch effect and visual appeal of the fireworks shells.
